2021 MX13 pac car dpf and scr efficiency issues in need of egr tuneup

[mikkhh]

there are no fault codes in ecm, have all comms etc, but now but no crank.

There had been lots of diagnosis done and cabin stuff unplugged etc etc beforehand .
There was also starter overheat message on cluster. No idea if it will crank with ecm no comms, most likely truck died and somebody cranked the hell out of it, batteries were completely dead when somebody first started diagnosing truck...

Most likely connector pins are bent oversize from tester leads etc from "diagnosis expertise", or maybe just some connecter not plugged in.


Well the truck started when power directly to starter solenoid. It is in max derate 20kmh, maybe that is why no crank. Not sure if MX13 has countdown hours for no start or not
